| Quercetin is a flavonol widely present in fruits and vegetables, particularly onions and apples. |
|
| In this case, the researchers increased the flavonol and anthocyanin content of tomatoes. |
|
| The flavonol group of polyphenols contained aglyconic quercetin and myricetin, traces of kaempferol as well as their various glycosides. |
|
| But the research was the first to show that nearly half of the total flavonol content of whole berries was left behind in the pomace instead of making its way into juice. |
|
| The higher antimicrobial activity of extracts from the leaves, compared to extracts from the fruit, could be attributed to flavan-3-ols and other flavonol glycosides. |
|
| Ellagic acid is the most abundant phenolic compound in cloudberry and red bramberry. In red berries the major flavonol group present is the anthocyanins. |
